Chosen Solution
Hi all, I’ve been having a go at fixing my sisters iPhone 5s that she drowned and probably tried to turn on but its dead.. So far I gave the board a full Isopropyl bath, and desoldered the EMI shields and cleaned all under them, however in the process I knocked a few capacitors(?) off near the 3 screen connecters on the board, its now a total of 4 since I had to remove another 2 to re-tin the contacts. So now my problem is how to reattach them to the board? Consider that the smd’s are under 1mm, so even my smallest chisel tip can’t do it. Thanks in advance, Seb
EDIT: You can’t see from the picture but the 2 smd chips on the right hand side are actually still attached, its the other 4 that aren’t.
Seb Stobbe, all the components you knocked off are part of the WLAN/BT circuitry. No exotic SMD components, just resistors and capacitors. Unless you know how to microsolder, there is no easy way to reattach them. If you do not have the tools, I would suggest that you find someone that may help you. You could contact this user and see if it can be fixed for a reasonable cost.

Hi Seb, It sounds like you’ve gotten some good advice here. I would only add a suggestion that you first measure across the + and - battery pins to see if there is a full short somewhere on this board. If so, you’ll need to identify and remove the short before any of this work would even matter. This phone should be able to turn on and function pretty well in many ways without any of these components. In a normal phone, you should measure very high resistance, aka “1”, across the battery connector. If you have a beep at continuity testing, or very low resistance then you have bigger fish to fry with this phone. You’d need to see if you can find the source of the shorted component and replace it. A donor board comes in very handy for this type of work—if you can find one that is the same phone but perhaps a victim of some other problem than water damage, you may find it more economical than attempting to buy each potential component individually. best of luck jessa
